[Snowtractor]

I say no. Look at the front drive sprocket the red one is identical to the Muskeg tractor and different than the armoured snomo. Also the rear tunnel area the steel extends down and on the snomo it is sqare-ish and round ( as in the pic ) on the muskeg. The drive shaft you se may just be a PTO to drive the dump for the rear deck on the muskeg or it could be a hydraulic , though I think PTO. Why send a drive shaft back to drive the front sprocket when you could just reverse the engine and put the tranny in front. All that aside the outside support structure is identical to the muskeg.As for exhaust you can run it anywhere to exit the vehicle. I might add that the muskeg tractor hull was used in a bunch of different configurations both offered and special order. What we need is more pics.
